The degree of disability depends on the severity and the type of illness experienced. Studies that compare the level of disability between people with chronic medical conditions and mental illnesses in North-Central Nigeria are scarce. This study aims to compare the disability levels between people with schizophrenia and Type 2 Diabetes Mellitus (T2DM) attending outpatient clinics at the Jos University Teaching Hospital, north-central Nigeria, and evaluate the factors associated with these conditions. <strong>Methods:</strong> It was a cross-sectional study with a total of 600 patients who were diagnosed with schizophrenia and T2DM, attending the Psychiatric and medical outpatient clinics of the Jos University Teaching Hospital, north-central Nigeria, between June 2017 and November 2017. The study assessed Psychotic and non-psychotic symptoms by applying the Brief Psychiatric Rating Scale (BPRS) among those with schizophrenia. We evaluated the level of disability by using World Health Organization Disability Assessment Schedule version 2.0 (WHODAS 2.00). <strong>Results:</strong> Disability was significantly higher among respondents with schizophrenia than those with T2DM. This difference occurred across all the domains except domain 2 (moving around). Marital status, living situation, occupation, and treatment adherence were significant common factors associated with disability in these conditions. In contrast, age, educational status, income level, and duration of illness were significantly associated with disability among respondents with T2DM only. <strong>Conclusion:</strong> Disability and its associated factors among people with chronic diseases, if identified early and proper interventions instituted, disability can be avoided or minimized among people with chronic illnesses.展开更多

Multiple scanning systems were evaluated to identify optimal approaches for point cloud processing and subsequent development of parameterized solid models, facilitating comprehensive morpho-geometric characterization. Experimental work was performed at the 3D Scanning Laboratory of SEDIC (Industrial Design and Scientific Calculation Service) at the Technical University of Cartagena, employing five distinct scanner types based on structured light, laser, and infrared technologies. Test specimens—including preliminary calibration using a lentil and biological analysis of a human crystalline lens—were digitized under rigorously controlled environmental conditions. Acquired point clouds underwent processing in Rhinoceros software to produce digital surface meshes, which were subsequently converted into solid CAD models via SolidWorks. Model fidelity and biomedical relevance were assessed through quantification of geometric and physical properties. Scanner performance varied significantly in reconstruction precision and resolution, with structured blue light systems (e.g., Artec SPIDER) exhibiting superior capability for capturing lens surface topography compared to infrared or white light alternatives. Resultant models enabled accurate dimensional analysis of clinically relevant parameters including volumetric and surface area measurements. Technology-specific advantages and constraints were rigorously cataloged relative to sample attributes. Findings indicate that structured blue light scanning provides the most effective foundation for crystalline lens digitization and modeling. The presented methodological approach not only ensures high-fidelity solid model generation but also demonstrates translational potential in medical domains, from custom intraocular lens design to refinement of ophthalmic therapeutic interventions.展开更多
